"-.The.. marking rollers I2 .are illustrated .more particularly. in Figures 1;4 and 5.1 and conllrseta circular member' 32. having a circularf-:bolf-,erSafor rotatable mountingsthereof on;the shaftrmeans 25,` and i a printin g strip 34 extending.; circumferentiallyv about 4the periphervof the, memberfl Fonpurposes of. illustratiomthastrip has 'formed thereon, suitable indicia suchgas a; numeral.,;13e peated. at spaced. intervals.

Two sets of rollers, each numberedfromgzero through nine respectively are provided with the aoeaso? device so that the rollers may be used in combinations providing numbers from one to ninetynine. Where it is desired to provide numbers from one to nine, a single roller is used (Figure 1) which is positioned between spacing rollers 35 each being half the width of a roller I2. Where it is desired' to provide numbers from ten to ninety-nine a pair of rollers is used (Figure 4), the spacing rollers being unnecessary since the width of the rollers is such to take up the space between the legs I6 and I'I. It will be understood that the width of the rollers I2 and the spacing rollers 35 may be such that three or four rollers may be mounted side by side on the shaft means to thereby provide numbers from one to nine thousand and ninety-nine.

Where two or more rollers Iare used together, it is desired that they are aligned and rotate as a unit. For this purpose, each of the rollers I2 is provided with an eccentric bore 3e having countered portions 3'I at each end. A suitable element 39, such as shown in Figure 6, is utilized for locking the rollers I2 for simultaneous rotation. This element has end portions 4I) each yadaptedto extend into the bore 36 of adjacent rollers and has an enlargement 4I between its ends adapted to extend into the counterbored portion 3l of adjacent rollers.

The marking medium applying roller I4 is illustrated in Figures 1 and 3 and comprises a spool member 42 having a flange 44 at one end and a central bore 45 provided with a counterbored portion 46 at the end opposite the flanged end. A tubular inking pad 4`I or the like is mounted on the spool and is removably positioned thereon by a member 49 having a flange 59, a bearing portion 5I fitting into the counterbored portion, and a central bore 52.

The roller I4 is rotatably supported intermediate the handle I5 and the roller I2, with its inkingl pad in contact with the roller I2, by a shaft 54 having a head 55 at one end and extending through apertures in legs IB and I1 and through the bores 45 and 52 of the members 42 and 49, respectively. The shaft is removably secured to the legs to facilitate replacement of the inking pad 4'I by a set screw 56 threaded into an aperture partially formed by the leg I I and partially formed by the end of the shaft opposite the head 55.

The shaft means 25 when attached as shown and the shaft 54 serve to reinforce the frame of the device, particularly to maintain the legs I6 and I'I in their parallel position and to prevent spreading thereof during use of the device.

In operation, when it is desired to interchange the rollers I2, the portion 2l is engaged and urged downward-ly to cause the circumferentially recessed portion 26 to be disengaged by the bifurcated portions 30. The shaft means is then adapted to be swung downwardly about its pivotal connection and away from the leg I'I, whereby rollers I2 and spacing rollers 35 can be slipped over the free end of the shaft means to remove or replace the same. When interchanging of the rollers has been effected, the shaft means is again connected to the leg I1. These operations can be easily effected in a minimum time interval.

While the device in accordance with the invention is useful for numerous purposes, it is particularly useful in the printing art where it is desired to number galley strips so that printed articles can be readily identified after editorial changes are effected, such as cutting, inserting and arrangement.

From the foregoing description, it will be seen that the present invention provides an improved marking device wherein the marking rollers are readily interchanged and the marking medium applying means are readily replaced. The device is simple in construction, economical in manufacture and is easily manipulated. The device can readily withstand such usage to which it may be subjected for its intended purpose.

As various changes may be made in the form, construction and arrangement of the parts herein, without department from the spirit and scope of the invention and without sacricing any of its advantages, it is to be understood that all matter herein is to be interpreted as illustrative and not in any limiting sense.

It is also to be understood that the following claims are intended to cover all the generic and specific features of the invention herein described, and all statements of the scope of the invention which, as a matter of language, might be said to fall therebetween.

I claim:

1. A marking device of the class described, comprising a frame having a pair of spaced apart parallel legs each provided with a free end and having ahandle portion at the opposite ends of said legs, a shaft, a hinge element at one end of said shaft, means pivotally connecting said element to the free end of one of said legs, in a manner whereby said shaft is mounted for tilting movement about an axis substantially perpendicular to the longitudinal axis of said shaft marking roller means removably mounted on said shaft and providing a close fit between said legs, a second shaft removably mounted on said legs between said handle portion and said first shaft and parallel to said rst shaft, inking roller means removably mounted on said second shaft in contact with said marking roller means and providing a close fit between said legs, means for detachably securing said second shaft on said legs, and positive locking means including cooperating elements at the free end of said leg other than said leg on which said hinge element is pivotally connected and at the other end of said first shaft, respectively, for detachably securing said first shaft, to said other leg and maintaining said legs in parallel relation at the free ends thereof the aforementioned arrangement of both of said shaft securing means and the close fit of said marking and said inking roller means between said legs providing a rigid structure whereby said shafts are maintained in parallel relation.

2. A marking device according to claim 1, wherein said locking element means for said first shaft include yieldable split fingers on said leg formed with opposed recesses and a reduced section on said first shaft of a width about equal to the thickness of said ngers adapted to be forced between said fingers and seat in said opposed recesses to positively lock said shaft and said leg and adapted to cooperate with the pivotal connection to rigidly connect said legs.

3. A marking device according to claim 1, wherein said inking roller means include a spool having a flange at one end thereof and a central shaft receiving bore provided with an enlarged bore portion at the end opposite said flange, a tubular inking medium applying member removably mounted on said spool and a member having a shaft receiving bore, a portion seated in said enlarged bore portion and a flange cooperating with said first flange to position said tubular member on said spool, said last mentioned member and said spool each having an outer portion in contact with one of said legs to maintain the same in assembled relation.

4. A marking device according to claim 1, wherein said marking ,roller means include a plurality of independent rollers having means for removably interconnecting and aligning the same for simultaneous rotation about said rst shaft.
